The Jacobs Ladder Adjustable 13-5/8in (Medium) from ALLSTAR PERFORMANCE is a precision-engineered suspension component designed for sprint cars and high-performance racing applications. This chromoly ladder frame serves as a critical lateral stability element, controlling chassis flex and maintaining consistent geometry under extreme cornering loads. Built for competitors who demand repeatable handling characteristics and maximum chassis control on dirt and asphalt surfaces, this adjustable design allows tuners to dial in the exact compliance curve their specific setup requires.
Constructed from chromoly steel and finished in durable black paint, the Jacobs Ladder features adjustable mounting points that let you fine-tune suspension kinematics without full frame replacement. The medium 13.625-inch length balances lateral stiffness with controlled flex, preventing the chassis from binding while maintaining the precise roll center location essential for consistent lap times. The hardware and strap assembly system allows secure mounting to both frame and suspension pickup points, accommodating the high-frequency vibrations and multi-directional forces inherent in sprint car racing. At 2.1 lbs, the compact footprint and lightweight design minimize unsprung mass while delivering the structural integrity required for competitive environments.
Sprint car builders and suspension specialists rely on adjustable ladder frames to dial in handling balance without expensive frame modifications. The medium size suits chassis ranging from tight-handling setups to more forgiving configurations, making it ideal for teams testing geometry changes mid-season. Installation requires basic mechanical knowledge and standard tools—secure the straps to your existing frame and suspension mounts, ensuring all hardware is torqued to manufacturer specs. This component integrates seamlessly with standard sprint car suspension systems and pairs effectively with adjustable trailing arms and panhard bars for comprehensive lateral control tuning.
